This Week in Elasticsearch - March 04, 2015

Welcome to This Week in Elasticsearch. In this roundup, we try to inform you about the latest and greatest changes in Elasticsearch. We cover what happened in the GitHub repositories, as well as many Elasticsearch events happening worldwide, and give you a small peek into the future of the project.

IndexSearcher's optional ExecutorService, which runs queries concurrently across segments to trade throughput for lower per-query latency, now supports arbitrary Collectors. This also adds a new IndexSearcher.count method to see how many hits a query matches.

For our lovely users of Kibana, we've prepared a set of video tutorials to get up to speed with all the new features in Kibana 4. These short videos will teach you more about navigation and creating pie charts. For folks more familiar with Kibana 3, we've got how-tos on migrating your Hits and Terms panels to K4.

Looking for more in-depth information on K4? You may enjoy the video from our recent webcast, What's New in Kibana 4. (registration required)

From the even more Kibana 4 love department: Alexandre Eleuterio Santos Lourenco concludes a three-part article series on the ELK Stack for your centralized logging needs with a how-to on setting up Kibana 4 and its feature set, including building visualizations. Awesome walk through with lots of screenshots within for the visually-oriented learner.

Looking to use Elasticsearch on AWS? As a follow on from our recent webcast, we've published a how-to guide that dives into the details of sizing your clusters, from RAM through to disk and network considerations. Check it out and let us know what you think.

Looking for a how-to on setting up Elasticsearch on EC2 using Vagrant? Look no further than this article from Ricardo Vegas. Great step-by-step instructions for folks looking to kick the tires quickly.

Haven't yet discovered the power of Elasticsearch Aggregations? Tony Messias published an excellent introduction, including plenty of code snippets so you can see what's going on under the hood.

Slides & Videos
